MANAGING A DISTRIBUTED NETWORK OF FUNCTION EXECUTION ENVIRONMENTS

Systems, methods, and computer-readable media for managing a distributed network of function execution environments. In some examples, a function router registers a plurality of execution endpoints on a catalog of execution endpoints and functions, each of the plurality of execution endpoints including a respective runtime environment capable of executing one or more functions. The function router receives, from a client, a request to execute a particular function and, based on the request, queries the catalog for the particular function and execution endpoints associated with the particular function. The function router receives a query response identifying one or more execution endpoints associated with the particular function, and selects an execution endpoint for executing the particular function based on one or more criteria associated with the request. The function router then sends to the client a response identifying the execution endpoint selected for executing the particular function.
